Hertel 89322069 Drill Bit Letter C 118 Point Hss

Product Description

The HERTEL 89322069 is a screw machine length drill bit designed for general-purpose drilling in metal, plastic, and similar materials. It is ground from high-speed steel (HSS) with a bright, uncoated finish and features a standard 118-degree split-less point. The screw machine length body is shorter than a jobber-length bit, which reduces deflection and improves rigidity in drill press, turret lathe, and screw machine applications. The overall length is 2.5 inches with a flute length of 1.375 inches. The right-hand cutting direction is standard for conventional drilling operations. This bit is sized to Letter C, equal to 0.2420 inches in decimal equivalent.

This bit is well suited to production environments and machine shop applications where shorter tooling improves repeatability and reduces chatter. It fits standard drill chucks on drill presses, CNC turning centers, screw machines, and hand-held drill motors. The Letter C size is commonly used when drilling pilot holes and clearance holes for fasteners in the 0.2420-inch diameter range. General-purpose HSS construction makes it appropriate for low-to-moderate speed cutting in ferrous and non-ferrous workpieces.

• Right-hand cut, compatible with standard drill chucks and machines

Compatibility

Designed as a general-purpose screw machine length drill bit compatible with standard drill chucks accepting Letter C or 0.2420-inch diameter tooling on drill presses, screw machines, and CNC equipment.

Installation Notes

This bit is installed and used by machinists and tool-and-die professionals in machine shop environments. Secure the shank fully in the drill chuck and verify runout before commencing a cut. Use appropriate cutting fluid when drilling ferrous materials to extend tool life and maintain dimensional accuracy. Inspect the cutting edges for wear before each use and replace the bit if the point is chipped or worn to prevent inaccurate hole sizing.
